This series is based on the previous patchset from Chen Fan: https://lists.nongnu.org/archive/html/qemu-devel/2014-05/msg02360.html
We try to make cpu hotplug with device_add, and make "-device foo-x86_64-cpu" availableļ¼also we can set apic-id property with command line, if without setting apic-id property, we offer the first unoccupied apic id as the default new apic id. When hotplug cpu with device_add, additional check of APIC ID will be done after cpu object initialization which was different from 'cpu_add' command that check 'ids' at the beginning. --- Changelog since RFC: -split out APIC vmstate/QMP-monitor changes into separate patches. -add the handle of the startup cpus(-device foo). -remove duplicated checking about env->cpuid_apic_id. -do actual APIC ID allocation at realize time if it is not set before. -remove the unneeded x86_cpu_cpudef_instance_init(). -split off device_del support out here. --- Chen Fan (2): cpu: introduce CpuTopoInfo structure for argument simplification cpu: add device_add foo-x86_64-cpu support Gu Zheng (4): qom/cpu: move register_vmstate to common CPUClass.realizefn qom/cpu: move apic vmstate register into x86_cpu_apic_realize monitor: use cc->get_arch_id as the cpu index acpi:cpu hotplug: set pcmachine as icc bus' hotplug handler cpus.c | 4 ++- exec.c | 32 +++++++++++++--------- hw/acpi/cpu_hotplug.c | 5 +++- hw/cpu/icc_bus.c | 15 ----------- hw/i386/pc.c | 6 ---- hw/i386/pc_piix.c | 6 +++- hw/i386/pc_q35.c | 5 +++ hw/intc/apic_common.c | 3 +- include/hw/cpu/icc_bus.h | 14 ++++++++++ include/hw/i386/apic_internal.h | 3 ++ include/qom/cpu.h | 2 + monitor.c | 4 ++- qom/cpu.c | 2 + target-i386/cpu.c | 54 +++++++++++++++++++++++++++++++++++--- target-i386/topology.h | 51 +++++++++++++++++++++++++----------- 15 files changed, 145 insertions(+), 61 deletions(-) -- 1.7.7
